These things are bad, which is why the FCC is saying it will not apply these provisions. For example, even today most municipalities set a regulated rate for basic cable service. It averages about $20/month nationwide, and doesn't come close to covering the cost of actually building a modern cable network out to a neighborhood.
Unbundling kills investment into the network, because why spend billions of dollars on infrastructure that you'll have to lease out at wholesale prices to your competitors?[1]
My theory is that unbundling is what killed DSL as a competitor to cable here in the U.S. FTTN has been quite successful in the U.K.,[2] as a gradual scheme for building fiber further into the network, with a last-hop of VDSL that can get faster as it gets shorter. There has been little FTTN deployment here in the U.S., because there's just no way for telcos to recoup the billions of dollars spent on fiber if they're forced to lease the VDSL at the other end to competitors for a song.
[1] See this Brookings Institute (not exactly a conservative hotbed) analysis, which calls the U.S. experiment with unbundling "disastrous" and concludes that it reduces capital investigate. http://www.pff.org/events/eventpowerpoints/022207BrusselsCom....
